Below are listed the 15-limit dyadic chords of sqrtphi temperament, subject to the condition that no interval smaller than 12/11, at 150 cents, appears. The essentially just chords are typed as otonal, utonal, or ambitonal. Those requiring tempering only by 325/324 are labeled marveltwin, by 364/363 gentle, by 540/539 swetismic, by 676/675 island, and by 1575/1573 nicolic. Codimension two temperaments are labeled swetismic-gentle, island-gentle and kleismic-marveltwin according to two commas which define it.
Sqrtphi has MOS of size 5, 8, 11, 14, 17, 20, 23, 26, 49 and 72. The largest chords on these lists have complexity 70, and so would require the 72 note MOS, but there are many chords of much lower complexity. Sqrtphi has a generator very close to √φ = √((1+√5)/2), which can be chosen to be exactly √φ. Either way, aside from the dyadic chords, chords with stacks of φ are interesting since φ² - φ = 1, resulting in a relationship between difference tones. Though it isn't the "official" 13/8 of sqrtphi, φ is only 7.44 cents flat of 13/8 which is close enough for government work. Chords such as 0-2-4-8-10 containing stacks of φs composers might find of interest.
